Chronic regurgitation among persons with mental retardation: a need for combined medical and interdisciplinary strategies.

A survey of institutionalized adults with severe mental retardation and chronic regurgitation was conducted. A high prevalence of dysphagia and gastroesophageal abnormalities was found. Many of these abnormalities require further evaluation and treatment prior to the diagnosis of rumination. More studies are needed to explore the causes and treatment approaches for chronic regurgitation in adults with developmental disabilities.
